Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a folding top plate structure and a wood-fired stove having the same structure. Background Technology

[0002] A wood-fired stove uses firewood, sawdust, shavings, weeds, corncobs, straw, and other firewood as fuel. Utilizing its unique stove structure, it combines and promotes the combustion of fuel through direct wood combustion, wood carbonization, and wood gasification, thereby achieving strong firepower and energy saving.

[0003] However, the existing wood-fired stoves have a relatively simple structure and an unreasonable layout. They require space inside the stove to place appliances such as steamers, which makes the overall size of the wood-fired stove relatively large and inconvenient to take out and use appliances such as steamers.

[0004] Meanwhile, during the use of a wood-fired stove, it is necessary to open the stove door occasionally to add fuel to the stove. However, during the process of opening the stove door, the smoke produced by the combustion of fuel is easy to escape from the stove door. The high-temperature smoke can not only burn and fumigate the human body, but also easily cause safety hazards such as fire. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a folding top plate structure and a wood-burning stove having the same structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A folding top panel structure includes a back panel, on which a top panel is rotatably mounted. A shelf is provided at the upper end of the top panel, and a light panel is provided at the lower end of the top panel. Insertion holes are provided on both sides of the back panel, and pins corresponding to the positions of the insertion holes and inserted and fixed into the insertion holes are provided on both sides of the top panel.

[0008] Preferably, the top plate has rotating holes on both sides, the back plate has a rotating plate rotatably connected to the rotating holes, and the back plate has two vertically distributed insertion holes on both sides.

[0009] Preferably, the rotating plate has a wire hole, and a pressure plate that abuts against the side wall of the top plate is installed on the rotating plate.

[0010] This utility model also discloses a wood-fired stove, including a folding top plate structure, a stove shell, and a gasifier disposed within the stove shell. The back plate is disposed on one side of the stove shell. The gasifier is provided with an inner furnace liner. An outer furnace cover is provided at intervals on the outer side of the inner furnace liner. An air inlet is provided on the outer furnace cover. A feeding trough is provided on one side of the inner furnace liner. A feeding port communicating with the inner furnace liner is provided in the feeding trough. Air curtain holes are provided at intervals on the feeding trough. The air curtain holes are inclined towards the inner furnace liner.

[0011] Preferably, the stove shell also includes a blower and a fan, the blower's air supply pipe is connected to the air inlet, the back panel has an exhaust fume duct, and the fan is connected to the exhaust fume duct.

[0012] Preferably, a cleaning groove is installed on the bottom plate of the furnace liner, and a grid plate is provided on the cleaning groove inside the furnace liner. An air inlet is provided at the bottom of the furnace liner, and a through hole is provided on the cleaning groove to cooperate with the air inlet and connect the air inlet to the inside of the furnace liner.

[0013] Preferably, the furnace liner is also provided with air inlet hole 2 and air inlet hole 3, which are distributed from bottom to top on the side wall of the furnace liner.

[0014] Preferably, a partition is inserted into the lower part of the cleaning trough, and a dust collection trough corresponding to the upper and lower parts of the cleaning trough is provided below the partition.

[0015] Preferably, the outer side of the furnace cover is provided with a surrounding plate at intervals, and the space between the furnace cover and the surrounding plate is filled with heat insulation cotton.

[0016] Preferably, the upper end of the furnace cover is provided with a fire-collecting plate, one side of the fire-collecting plate is connected to a smoke exhaust pipe, and the pot body is provided on the fire-collecting plate.

[0017] The beneficial effects of this utility model are:

[0018] 1. By rotating the top plate onto the back panel, the top plate is horizontally placed on the back panel, allowing the use of the shelf on the top plate to place steamers, steaming baskets, and other utensils. At the same time, it is also convenient to take out and use steamers and other utensils during cooking, making the use of the wood-fired stove more convenient. Its structure is also more compact and reasonable, greatly reducing the volume and saving space. When the top plate is rotated vertically onto the back panel, the top plate can avoid obstructing the cooking of the wood-fired stove, so that even steaming utensils with a high stacking height can meet the cooking needs, making the practicality of this wood-fired stove better.

[0019] 2. Inclined and spaced air curtain holes are set on the feed chute of the furnace liner. When air is supplied in through the air inlet, the flowing air forms an air curtain airflow that blocks the feed inlet through the air curtain holes. This air curtain airflow prevents the flue gas from overflowing from the feed inlet, thus avoiding burns and fumes from the high-temperature flue gas when adding fuel, making the use of the wood-fired stove safer and more reliable.

[0020] 3. Air inlet hole one, air inlet hole two, and air inlet hole three are sequentially opened on the side wall of the furnace liner. Air inlet hole one supplies air to the fuel burning in the furnace, providing sufficient oxygen for fuel combustion. At the same time, air inlet hole two and air inlet hole three respectively provide secondary and tertiary oxygenation to the furnace liner, so that the particles in the flue gas can be burned more completely, resulting in higher fuel combustion utilization and greatly reducing the generation of soot and other substances in the flue gas.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] like Figures 1 to 11 As shown, a folding top panel structure includes a back panel 6, on which a top panel 7 is rotatably mounted. A light panel 74 is provided at the lower end of the top panel 7 to provide illumination when using a wood-fired stove. A shelf 73 is provided at the upper end of the top panel 7. By horizontally setting the top panel 7 on the back panel 6, the shelf 73 on the top panel 7 can be used to place steamers, steaming baskets, and other utensils. At the same time, it is also convenient to take out and use steamers and other utensils during cooking, making the use of the wood-fired stove more convenient. Moreover, its structure is more compact and reasonable, greatly reducing its volume and saving space.

[0036] Furthermore, the back plate 6 has insertion holes 63 on both sides, and the top plate 7 has pins 71 on both sides that correspond to the positions of the insertion holes 63 and are inserted and fixed in the insertion holes 63. The pins 71 are inserted into the insertion holes 63 so that the top plate 7 is horizontally fixed on the back plate 6 and the load-bearing structure of the top plate 7 is more stable.

[0037] Furthermore, the top plate 7 has rotating holes 72 on both sides, and the back plate 6 is provided with a rotating plate 62 rotatably connected to the rotating holes 72. The rotating plate 62 is inserted into the rotating holes 72 so that the top plate 7 can rotate relative to the back plate 6.

[0038] The rotating plate 62 has a wire hole 621, through which the lighting circuit on the lamp plate 74 can be passed. The rotating plate 62 is equipped with a pressure plate 65 that abuts against the side wall of the top plate 7. The pressure plate 65 is located inside the top plate 7 and abuts against the inner side wall of the top plate 7.

[0039] The back plate 6 has vertically distributed insertion holes 64 on both sides. When the top plate 7 is rotated to a vertical position, the pin 71 can be inserted into the insertion hole 64 to fix and limit the vertical rotation of the top plate 7. When the top plate 7 is rotated vertically onto the back plate 6, the top plate 7 can avoid obstructing the cooking of the wood-fired stove. That is, when it is necessary to cook steamers or other steaming utensils with a high stack, the vertical top plate 7 will not obstruct the use of the steaming utensils, so that steaming utensils with a high stack can also meet the cooking needs, making the practicality of this wood-fired stove better.

[0040] This embodiment also discloses a wood-fired stove, including the above-mentioned folding top plate structure, a stove shell 1, and a gasifier disposed inside the stove shell 1. The back plate 6 is disposed on one side of the stove shell 1, and the top plate 7 is rotatably installed on the back plate 6. The gasifier is provided with an inner furnace liner 2, and an outer furnace cover 3 is provided at intervals on the outside of the inner furnace liner 2. An air space is formed between the inner furnace liner 2 and the outer furnace cover 3 for air flow. An air inlet 31 is provided on the outer furnace cover 3 to supply air to the inside through the air inlet 31.

[0041] A feed trough 21 is provided on one side of the furnace liner 2. The feed trough 21 has a feed inlet 211 that connects to the furnace liner 2. The feed trough 21 is fixedly connected to the furnace liner 2. The feed trough 21 is used to add fuel to the furnace liner 2. The feed trough 21 has spaced air curtain holes 212. The air curtain holes 212 are inclined at the upper end of the feed trough 21, that is, the air curtain holes 212 are inclined towards the furnace liner 2. A cover plate 22 covering the air curtain holes 212 is provided on the feed trough 21. The cover plate 22 is connected to the furnace outer cover 3.

[0042] When air is supplied to the inside through the air inlet 31, the air flowing between the inner furnace liner 2 and the outer furnace cover 3 forms an air curtain airflow 213 that blocks the feed inlet 211 through the air curtain hole 212. The air curtain airflow 213 is inclined downward and inward to form an air curtain that blocks the smoke. Specifically, the air curtain airflow 213 prevents the smoke from overflowing from the feed inlet 211, thereby preventing the high-temperature smoke from overflowing and burning or suffocating the human body when adding fuel, making the use of the wood stove safer and more reliable.

[0043] Furthermore, the airflow 213 blows the air into the furnace liner 2 to increase the amount of oxygen required for fuel combustion, allowing the fuel to burn more completely. At the same time, the airflow 213 can also block the ash produced after the fuel combustion, preventing the ash from drifting outward and causing safety hazards.

[0044] A stove door 11 is rotatably connected to the stove shell 1, and the stove door 11 rotates to block the outer port of the feed trough 21.

[0045] The stove shell 1 is equipped with a blower 5 and a fan 8. The air supply pipe 51 of the blower 5 is connected to the air inlet 31 to deliver air into the air inlet 31 through the blower 5 and the air supply pipe 51. The back plate 6 is provided with an exhaust fume channel 61, and the fan 8 is connected to the exhaust fume channel 61.

[0046] A cleaning trough 4 is installed on the bottom plate 23 of the furnace liner 2. A grid plate 42 located inside the furnace liner 2 is provided on the cleaning trough 4. The fuel is placed on the grid plate 42 through the feed trough 21 for combustion.

[0047] The lower part of the furnace liner 2 is provided with an air inlet hole 24. The ash cleaning groove 4 is provided with a through hole 41 that cooperates with the air inlet hole 24 and connects the air inlet 31 and the interior of the furnace liner 2. External air is supplied to the fuel burning in the furnace liner 2 through the air inlet 31, the air inlet hole 24, the through hole 41, and the grid plate 42, thereby providing sufficient oxygen for the combustion of the fuel.

[0048] The furnace liner 2 is also provided with air inlet 25 and air inlet 3 26. The air inlet 1 24, air inlet 25, and air inlet 3 26 are distributed from bottom to top on the side wall of the furnace liner 2. The air inlet 25 and air inlet 3 26 respectively provide secondary and tertiary oxygenation to the furnace liner 2, so that the particles in the flue gas can be burned more completely, resulting in higher fuel combustion efficiency and greatly reducing the generation of soot and other substances in the flue gas. This also reduces the dense smoke and exhaust gas produced by combustion, making the use of this embodiment more environmentally friendly.

[0049] Furthermore, the air introduced into the furnace liner 2 through air inlet 25 and air inlet 3 26 is first heated by the side wall of the furnace liner 2, thereby making the air introduced through air inlet 25 and air inlet 3 26 high temperature air. The high temperature air further promotes the combustion of particles in the flue gas, so that the fuel can be utilized more fully.

[0050] A partition 43 is inserted into the lower part of the ash cleaning trough 4. The partition 43 is inserted into the ash cleaning trough 4 so that the ash cleaning trough 4 can temporarily collect the ash of the fuel combustion when the fuel is burning. A collection trough 44 corresponding to the ash cleaning trough 4 is provided below the partition 43. By moving the partition 43 outward, the ash of the fuel combustion in the ash cleaning trough 4 can fall into the collection trough 44 for cleaning.

[0051] The outer side of the furnace cover 3 is provided with a surrounding plate 32 at intervals. The space between the furnace cover 3 and the surrounding plate 32 is filled with heat insulation cotton to isolate the high temperature generated by the combustion of fuel in the furnace liner 2 through the heat insulation cotton and other heat insulation materials. The upper end of the furnace liner 2 is provided with an opening. The upper end of the furnace cover 3 is provided with a heat collection plate 33 to concentrate heat at the heat collection plate 33 through the opening at the upper end of the furnace liner 2 and the heat collection plate 33. A pot body 12 is provided on the heat collection plate 33, and a steamer or other steaming utensils can be placed on the pot body 12 to heat the pot body 12.

[0052] The space between the fire collecting plate 33 and the surrounding plate 32 is also filled with hot cotton, and a smoke exhaust pipe 34 is connected to one side of the fire collecting plate 33 to draw out the flue gas generated by fuel combustion.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
